Tau protein: a possible prognostic factor in optic neuritis and multiple sclerosis

Area of Science:

• Neuroscience
• Biomarker Discovery
• Neurology

Background:

• Tau protein is a potential biomarker for axonal damage and irreversible neurological impairment in Multiple Sclerosis (MS).
• Cerebrospinal fluid (CSF) tau concentrations may help assess the risk of progression from Optic Neuritis (ON) to MS.

Purpose of the Study:

• To investigate the association between tau protein and 14-3-3 protein concentrations in CSF.
• To compare these levels in patients with monosymptomatic ON versus those who progressed to MS.
• To evaluate findings against existing literature.

Main Methods:

• Analysis of CSF samples from 66 patients with MS and/or ON.
• Quantification of tau protein and 14-3-3 protein in CSF.
• Correlation of protein levels with clinical and paraclinical data.

Main Results:

• Significantly increased CSF tau protein in relapsing-remitting MS and ON patients who progressed to MS.
• No elevated tau protein detected in monosymptomatic ON patients.
• Tau protein concentration significantly correlated with Expanded Disability Status Scale (EDSS) score.
• 14-3-3 protein was not detected in any CSF samples.

Conclusions:

• Tau protein may serve as a prognostic factor for predicting the progression from ON to MS.
• Further research is warranted to explore the role of CSF tau protein in MS.
